In this book C.S. Lewis, in a dream, finds himself in a bus which travels between Hell and Heaven. This is the starting point for an extraordinary meditation upon good and evil which takes issue with William Blake’s The Marriage of Heaven and Hell.

The writer, in a dream, finds himself in a bus which travels between Hell and Heaven. This is the starting point for an extraordinary meditation upon good and evil which takes issue with William Blake’s The Marriage of Heaven and Hell. In Lewis’s own words, ‘If we insist on keeping Hell (or even earth) we shall not see Heaven: if we accept Heaven we shall not be able to retain even the smallest and most intimate souvenirs of Hell.’ “I think it is unlikely that if other books as generally entertaining ... appear this year, they will be as generally instructive.” W.H. Auden, Saturday Review
